From kindergartners to grad students, roughly 76 million Americans are heading back to the classroom this month--but not before they hit the mall. According to the National Retail Federation, parents shell out a whopping $54.1 billion on back-to-school gear, making it a retail season second only to Christmas. The economic downturn has taken a bite out of that apple, but deep discounts and tax holidays may give this season a boost. We'll do the math:

$594.24- The average amount spent on back-to-school stuff for each child

3,800,000,000- The number of wooden pencils sold per year
